The Tony Award-winning musical Monty Python's Spamalot will celebrate its third anniversary on Broadway March 18.

The musical, which is "lovingly ripped off" from the film "Monty Python and the Holy Grail," began its run at Broadway's Shubert Theatre Feb. 14, 2005, and officially opened March 17. The production made its world premiere at Chicago's Shubert Theatre Dec. 21, 2004-Jan. 23, 2005.

On March 18 there will be a special 3-D performance of Spamalot. "Of course the show is always performed in 3-D," press notes state, "but you get to wear really silly glasses at this special performance."

For a limited time, all triplets get in free when all three attend the show together. Spamalot features a book and lyrics by Eric Idle, music by John Du Prez and Eric Idle, direction by Mike Nichols, choreography by Casey Nicholaw and is based on the screenplay of "Monty Python and the Holy Grail" by Monty Python creators Graham Chapman, John Cleese, Terry Gilliam, Eric Idle, Terry Jones and Michael Palin.

The musical tells the tale of King Arthur and his Knights of the Round Table on their quest from God for the Holy Grail — with a short stop in the dazzling Spam-filled land of Camelot.

Spamalot earned the 2005 Tony Award for Best Musical and took home honors for direction (Mike Nichols) and one of its stars (Sara Ramirez).

On Broadway Spamalot plays Tuesday-Friday at 8 PM, Saturday at 2 and 8 PM and Sunday at 2 and 7 PM.
